- the through holes 14 evenly defined in the sleeve 12 are conical expanding from an inner side of the sleeve 12 to an outer side thereof.
- the minimum diameters of the through holes 14 are less than those of the balls 15 .
- the sleeve 12 comprises a free end away from the first end face 13 with a slot 16 defined in the outer wall thereof.
- a recess 18 is defined in the periphery of the first part 10 and in communication with the first end face 13 .
- a first blind hole 182 is defined in the first part 10 and in communication with the recess 18 .
- the first blind hole 182 is perpendicular to the first end face 13 .
- the first part 10 defines at least one curved sliding groove 19 in the first end face 13 and, in this embodiment, the first part 10 defines two symmetrically opposite curved sliding grooves 19 in the first end face 13 .
- the securing member 20 comprises an inner wall 22 and a second end face 24 .
- a plurality of protrusions 222 are configured on the inner wall 22 , wherein every two neighboring protrusions 222 define a notch 224 therebetween.
- the second end face 24 defines two openings 241 , 242 and at least one hole 244 . In this embodiment, the second end face 24 defines two symmetrically opposite holes 244 .
- a plurality of protrusions 222 are evenly disposed on the inner wall 22 and a plurality of notches 224 are defined between the neighboring protrusions 222 .
- the second part 30 comprises a body 31 with a columnar tail 32 fixed thereto, configured for reception in the sleeve 12 .
- the tail 32 is integrally formed with the body 31 .
- the tail 32 defines an annular groove 324 in the periphery thereof and at least one opening 326 in an end away from the body 31 .
- the locking block 40 comprises a first surface 42 , a second surface 44 opposite to the first surface 42 and a side surface 46 connecting the first surface 42 and the second surface 44 .
- a locking portion 422 located on the first surface 42 can match one of the openings 241 , 242 to lock or unlock the securing member 20 .
- the second surface 44 defines a second blind hole 442 .
- the securing member 20 is located around the sleeve 12 and the second end face 24 corresponds to the first end surface 13 .
- a stop collar 50 is fixed in the annular groove 16 and abuts the inner wall 22 of the securing member 20 , thereby applying tension on the inner wall 22 to restrict axial movement of the securing member 20 relative to the first part 10 .
- At least one positioning block 171 is located between the first part 10 and the second part 30 , limiting rotation thereof.
- the first part 10 defines at least one hole 17 , which communicates with at least one opening 326 of the second part 30 .
- One end of the positioning block 171 is fixed in the hole 17 and the other end is received in the opening 326 .
- the protrusions 222 guide the balls 15 into the annular groove 324 , positioning the second part 30 on the first part 10 on an axis, as the protrusions 222 of the securing member 20 correspond to the through holes 14 of the first part 10 .
- the protrusions 222 of the securing member 20 are away from the through holes 14 of the first part 10
- the notches 224 of the securing member 20 correspond to the through holes 14 of the first part 10 .
- the second part 30 is moved away from the first part 10 , the balls 15 can move into the notches 224 of the securing member 20 .
- the second part 30 is removable from the first part 10 .
- the locking block 40 is installed in the recess 18 of the first part 10 via a pin 47 , with one end fixed in the second blind hole 442 and the other movable end received in the first blind hole 182 .
- a spring 48 is located between the pin 47 and the bottom of the first blind hole 182 to impel the locking portion 422 into one of the openings 241 , 242 of the securing member 20 , such that the locking block 40 can move elastically relative to the first part 10 .
- the locking block 40 , the pin 47 , the spring 48 , the recess 18 , the first blind hole 182 and the openings 241 , 242 of the securing member 20 collaboratively limit rotation of the securing member 20 .
- At least one curved sliding groove 19 receives a spring 25 therein.
- One end of a pin 26 is received in the sliding groove 19 and fixed on one end of the spring 25 , while the other end of the pin 26 is received in the hole 244 of the securing member 20 .
- the pin 26 securely fits in the hole 244 .
- the pin 26 can also be screwed into the hole 244 or connected via other means.
- the locking block 40 When mounting the second part 30 onto the first part 10 , the locking block 40 is moved towards the first blind hole 182 of the first part 10 , and the second part 30 inserted into the sleeve 12 , and securing member 20 rotated to impel the ball 15 into the annular groove 324 via the protrusions 222 corresponding to the through holes 14 of the first part 10 . Upon its release, the locking block 40 moves toward the securing member 20 until the lock portion 422 is received in the opening 242 to lock the holding fixture. In this state, the spring 25 is compressed.
- Removal of the second part 30 from the first part 10 entails the locking block 40 moving toward the first blind hole 182 of the first part 10 until the lock portion 422 is removed from the opening 242 with the spring 48 being compressed.
- the unlocked securing member 20 can rotate along the sliding groove 19 under the force of the spring 25 together with the pin 26 and, accordingly, the protrusions 222 move away from the balls 15 .
- the balls 15 are allowed into the notches 224 of the securing member 20 .
- the locking block 40 moves toward the securing member 20 under the force of the spring 48 until the locking portion 422 is received in the opening 241 to lock the securing member 20 .
